This 3D map of the "Blitzenreuter Seenplatte", an nature reserve, gives the posibility to follow the way of water in this area. It is located in Blitzenreute, Baden-Württemberg, Germany.
Under the motto "water flows" a rotating cube asked the question, which way the water of the pond takes to the "Schussen" (a small river). The visitor is prompted to take water with his hands from the pond in the terrain model as to be able to follow the waters way. On the two other sides of the cube is the earlier question answered. At the same time the question is asked and also answers, in which sea this pond water flows.
